Xcode 4.2 on Lion— App store thinks the app is already installed

Question

Is any one seeing the issue I m facing. I am trying to upgrade to Xcode 4.2 on my Lion and the app store says it is Installed.

I had a developer preview of 4.2 may b

Answer 1

Yep, I had the same problem. Here's what fixed it for me:

1. Go to the Applications folder and delete Install Xcode.app.

2. Go to .Trash in your home directory, and manually delete Install Xcode.app. I did this in Terminal.app by typing the following:

   sudo rm -rf Install\ Xcode.app

You could of course combines steps 1 and 2 by executing the sudo rm command right in the Applications folder, but I felt a little safer doing it this way.
